Variable Offset Shell for 3D Contextual Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer graphics editing techniques using two-dimensional inputs for three-dimensional objects are time-consuming and user-intensive, as users must continuously manipulate the object to view edited points accurately.
Innovation Solution
A method and system that constrain point movement on a three-dimensional object using a processing element to render a shell defining an offset distance, allowing users to edit points in one or two dimensions while maintaining context without rotating the object, by limiting movement along specific axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-dimensional inputs are used to edit three-dimensional objects, then the editing interface is simplified and easier to operate, but the user must continuously manipulate the object to view edited points accurately, increasing time consumption and user effort
Solution Approach 1:
The patent introduces a shell that is offset from the three-dimensional object by a specified distance, creating a fourth dimensional reference frame. This shell provides contextual boundaries that allow users to understand the three-dimensional position of edited points without needing to rotate or manipulate the object continuously. The offset shell transforms the editing experience by adding a reference dimension that preserves spatial context.
2Measurement precision
If the object is rotated or manipulated to view edited points in three dimensions, then the position accuracy can be determined, but the editing process becomes more time-consuming and user-intensive
Solution Approach 1:
The offset shell serves as an intermediary reference structure between the user and the three-dimensional object. Instead of directly manipulating and rotating the object to determine point positions, users interact with the shell which provides visual context and spatial boundaries. This intermediary structure allows accurate position determination while maintaining a static object view, thereby improving editing efficiency.
3Loss of information
If continuous object manipulation is performed to ascertain edited point positions, then accurate spatial understanding is achieved, but user effort and time increase significantly
Solution Approach 1:
The shell is pre-calculated and offset from the three-dimensional object by a specified distance before the editing process begins. This preliminary structure provides the spatial context framework in advance, eliminating the need for users to continuously manipulate the object during editing. The pre-established reference frame maintains spatial information integrity while reducing operational complexity.

AI summary
A method for editing content including at least one three-dimensional object. The method includes determining by a processing element one or more constraints, rendering by the processing element a shell defining an offset distance to the three-dimensional object corresponding to the one or more constraints, receiving a user input to a point related or connected to the three-dimensional object, and moving the point in a direction corresponding to the user input. In the method, the movement of the point is limited in at least one direction by the shell.
